THC
Delta-9 THC in its active form, already converted before any heat. On raw flower it is usually a small number sitting next to a large THCa.

- THCa
THC before it is heated. It is the big number on most flower labels; heat (a flame, a vape, an oven) turns most of it into THC. - Total THC
What the label works out you actually get: THCa converted, plus any THC already there. - CBN
Cannabinol, which forms as THC breaks down with time, heat, light and air. A higher CBN number on an older batch is one sign of how long it has sat and how it was kept.
